Hello, can someone tell me how I could solve the problem of the crash of unreal in the mac? I don’t know what happens but it happens to me very often.
I explain:
First I crashed due to a conflict with “Metal”. I updated the XCode and the problem is fixed. Now it crashes me included when I want to open a material. I have an iMac Pro memory: 32 GB 2666 MHz DDR4 and Radeon Pro Vega 56 8 GB Graphics, I don’t think it is the problem with the computer!
Here is the last error:
